KGO-CHANNEL 7 -- “This would be a case study in ethical, any journalism ethics class ... what not to do,” Yumi Wilson says. Wilson reported for the San Francisco Chronicle for 11 years. She’s now a Journalism professor at San Francisco State with a specialty in ethics. She says all newspapers, including the Examiner, Bay Guardian and SF Weekly owned by Todd Vogt, build their circulation based on objectivity. Wilson: “And then all of a sudden, behind the scenes, you’re directing editorial coverage based on a dollar amount, then you’re no longer objective.”
